The practical consequence of labeling is that it forces us to define what actually matters. RoberRed is right that grammar tools blur the line, but so do food labels: we don't call a sandwich organic because the lettuce was, and we don't require warning labels for trace allergens. The law can set a meaningful threshold, say, AI generating a substantial portion of the text or visuals, not fixing typos or filtering a photo. That's not confusing; it's how regulation works everywhere. Without that baseline, we let the perfect be the enemy of informed consent, and readers lose the context they need to judge what they're seeing.
